A protester has been charged with disorderly conduct after yelling at former President Bill Clinton during a campaign stop.

The Corpus Christi Caller-Times says that the man was holding a sign saying the Sept. 11 attacks were an inside job as Clinton spoke. The man yelled at Clinton later as the former president shook hands with the crowd.

Police were approaching the man when someone in the crowd grabbed his sign and tore it in half. The paper says the unidentified man screamed at officers to protect his First Amendment rights. Police handcuffed the man and took him to a patrol car and said he would be charged with disorderly conduct.

Campaigning for his former first lady, Democratic presidential candidate Hillary Rodham Clinton, he spoke Monday to fewer than 1,000 people in a gym at the University of Texas-Pan American in Edinburg, touching on his wife's plans to reinvigorate the economy, provide health insurance and make college affordable.

In his 17-minute speech, Clinton did not mention his wife's rival, Barack Obama. Obama spoke to more than 5,000 on the campus two weeks ago.

Last month, the former president had an angry response to another 9/11 protester, as RAW STORY reported.

"9/11 was not an inside job, it was an Osama Bin Laden job," Clinton said at a campaign event in Denver.

"We look like idiots, folks, denying that the people who murdered our fellow citizens didn't when they are continuing to murder people all around the world," he added. "So we heard from you, you go away."
